The Golden Age of Kiev
The region of Kiev dominated the state of Kievan Rus' for the next two centuries (see fig. 2). The grand prince of Kiev controlled the lands around the city, and his theoretically subordinate relatives ruled in other cities and paid him tribute. The zenith of the state's power came during the reigns of Prince Vladimir (r. 978-1015) and Prince Yaroslav (the Wise; r. 1019-54). Both rulers continued the steady expansion of Kievan Rus' that had begun under Oleg. To enhance their power, Vladimir married the sister of the Byzantine emperor, and Yaroslav arranged marriages for his sister and three daughters to the kings of Poland, France, Hungary, and Norway. Vladimir's greatest achievement was the Christianization of Kievan Rus', a process that began in 988. He built the first great edifice of Kievan Rus', the Desyatinnaya Church in Kiev. Yaroslav promulgated the first East Slavic law code, Rus'ka pravda
(Justice of Rus'); built cathedrals named for St. Sophia in Kiev and Novgorod; patronized local clergy and monasticism; and is said to have founded a school system. Yaroslav's sons developed Kiev's great Peshcherskiy monastyr' (Monastery of the Caves), which functioned in Kievan Rus' as an ecclesiastical academy.
Vladimir's choice of Eastern Orthodoxy reflected his close personal ties with Constantinople, which dominated the Black Sea and hence trade on Kiev's most vital commercial route, the Dnepr River. Adherence to the Eastern Orthodox Church had long-range political, cultural, and religious consequences. The church had a liturgy written in Cyrillic (see Glossary) and a corpus of translations from the Greek that had been produced for the South Slavs. The existence of this literature facilitated the East Slavs' conversion to Christianity and introduced them to rudimentary Greek philosophy, science, and historiography without the necessity of learning Greek. In contrast, educated people in medieval Western and Central Europe learned Latin. Because the East Slavs learned neither Greek nor Latin, they were isolated from Byzantine culture as well as from the European cultures of their neighbors to the west.
In the centuries that followed the state's foundation, Rurik's purported descendants shared power over Kievan Rus'. Princely succession moved from elder to younger brother and from uncle to nephew, as well as from father to son. Junior members of the dynasty usually began their official careers as rulers of a minor district, progressed to more lucrative principalities, and then competed for the coveted throne of Kiev.
In the eleventh and twelfth centuries, the princes and their retinues, which were a mixture of Varangian and Slavic elites and small Finno-Ugric and Turkic elements, dominated the society of Kievan Rus'. Leading soldiers and officials received income and land from the princes in return for their political and military services. Kievan society lacked the class institutions and autonomous towns that were typical of West European feudalism. Nevertheless, urban merchants, artisans, and laborers sometimes exercised political influence through a city assembly, the veche,
which included all the adult males in the population. In some cases, the veche
either made agreements with their rulers or expelled them and invited others to take their place. At the bottom of society was a small stratum of slaves. More important was a class of tribute-paying peasants, who owed labor duty to the princes; the widespread personal serfdom characteristic of Western Europe did not exist in Kievan Rus', however.
